To all whom it may concern:

Be it known that 1, JAMES E. MAYER. a citizen of the United States,residing at Bluefield, in the county of Mercer and State of WestVirginia, have invented certain new and useful Improvements in CombinedDental Props and Mirrors; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

This invention relates to new and useful improvements in combined mouthprops and dental mirrors and comprises a simple and efficient device ofthis nature having various details of construction, combinations andarrangements of parts which will be hereinafter fully described, shownin the accompanying drawings and then specifically defined in theappended claims.

ll illustrate my invention in the accompanying drawings, in which:

Figure 1 is a plan view of my invention. Fig. 2 isa side elevation.

Reference now being had to the details of the drawings by letter, A andA designate respectively an upper and a lower lip shield,

and B, B designate portions of the frame which are bent to form loops C,the ends of which are fastened to the upper lip shield A, and at thepoint, designated by letter C, the frame is bent at acute angles for thepurpose of preventing the prop from slipping upon the teeth. The portionof the prop connected to the lower shield consists of the portions Ewhich are similar to the parts B before described and each is bent toform a loop E, while the portions E are bent at acute angles at pointsdesignated by letter E for the same purpose as described of the partsbent at B, that is in order to prevent the prop from slipping upon theteeth of the lower jaw. v

H is an outer ring forming a portion of the frame and an inner ring,designated by letter I, is provided with countersunken holes for thereception of the screws G, the

heads of which are mounted in said countersunken holes and engagethreaded apertures in the ring H and form pivots for said ring I. i

A mirror, designated by letter N, is provided with diametricallyopposite pivots LT connecting the same with the ring H midway betweenthe pivotal points of the latter, thus allowing the mirror to have auniversal pivotal movement as will be readily understood.

In adapting the device for use, cotton is inserted in the loops andagainst the lip shields, after which the shields are placed against theupper and lower lips with the acute angle portions of the frame passingover the edges of the teeth of the upper and lower jaw and which wouldposition the mirror within the mouth and so located that it may betilted'at any angle whereby the operator may conveniently see anyportion of the interior of the mouth.

By the peculiar construction of dental prop made in accordance with myinvention, it will be noted the rows of cotton may be readily removedand replaced at will without removing the prop from the mouth of thepatient.

What I claim to be new is:

1. A combined dental prop and mirror comprising lip shields, a framehaving arms which are bent to form loops integral with said shields,loops adapted for the reception of cotton, said frame having portionsbent at angles, and a swiveled mirror mounted upon said frame.

2. A combined dental prop and mirror comprising lip shields, a framehaving arms which are bent to form loops and secured to said shields,loops adapted for the reception of cotton, said frame bent at acuteangles and extended rearwardly, said frame having a circular outlinedportion, a ring swiveled to the frame, and a mirror swiveled to thering. a

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

JAMES ERLE MAYER.
